Informationen zum Autor The American Institute of Chemical Engineers (AIChE) is a distinguished professional association that strives to provide leadership in advancing the chemical engineering profession. The Equipment Testing Procedures Committee is composed of engineers with substantial experience in the design and operation of process plants, as well as in solving problems that can arise with the equipment used in these plants. Klappentext The first edition of the AIChE(r) manual on evaluating positive displacement pumpsPositive Displacement Pumps: A Guide to Performance Evaluation is the latest text in the AIChE(r) Equipment Testing Procedure series. It provides pump users with concise, easy-to-follow procedures for testing various types of pumps in the field. The manual covers both traditional and state-of-the-art testing methods and takes into account the "imperfect" realities of actual field conditions. User-friendly and complete with numerous helpful illustrations and tables, this reference includes:*Definitions of major terms, with explanations, conversion factors, and nomenclature*Coverage of diverse types of positive displacement pumps: gear; lobe; multiple screw; vane; progressive cavity; diaphragm; and piston/plunger*Descriptions of test preparation logistics, safety precautions, instruments, methods of measurement, standardized tests, and other tests*Coverage of pump-testing for applications handling non-Newtonian fluidsThis is the hands-on reference for chemical engineers, plant managers, and other professionals responsible for evaluating positive displacement pumps. It fills the gap between manufacturers' literature and textbooks and provides practical, effective guidance on troubleshooting and problem-solving in the field. Zusammenfassung Positive Displacement Pumps is a current reference guide for positive displacement pumps for both traditional and state-of-the-art testing methods, and serves as a bridge between textbooks and manufacturer's literature by providing equipment testing practices based on technical know-how, practical experience, and academic theory.
